whole life insurance
Some people want a death benefit that is certain to pay out, no matter how long they live, plus a slowly growing pot of savings inside the policy they can borrow against. Term insurance cannot promise that, because it expires. Whole life insurance is the classic answer: coverage that lasts your entire life, with a level premium and a guaranteed, growing cash value.
Because a whole life policy must eventually pay a death benefit (everyone dies), the insurer cannot rely on the policy lapsing. So it charges a level premium that, in the early years, is far more than the cost of that year's mortality. The surplus accumulates with interest as a reserve, building the policy's cash value. Over decades this reserve grows toward the face amount; mathematically it is a savings element wrapped around pure protection. For example, a 35-year-old might pay a fixed 3,000 a year for life for a 200,000 benefit, with cash value climbing from near zero to tens of thousands over the years.
Actuaries see whole life as protection plus a forced-savings account, priced with conservative mortality and interest assumptions so the guarantees hold. It is far more expensive per dollar of cover than term, and the cash value grows slowly at first. The honest caveat: whole life is not primarily an investment, and its early surrender values can be low or zero, so it suits buyers who genuinely want lifelong cover and will keep the policy for decades — not someone who may cancel in a few years.
A 40-year-old pays a fixed 4,000 a year for life for 250,000 of whole life cover. In the first few years almost the whole premium goes to mortality cost and expenses, and cash value is tiny. By age 65 the accumulated reserve might be 90,000 in cash value, which he can borrow against or surrender — and the 250,000 is guaranteed to be paid whenever he dies.
Lifelong cover + a guaranteed, slowly growing cash value — for a much higher premium.
The cash value is not 'extra' money on top of the death benefit. On most traditional whole life policies, if you die the insurer pays the face amount and keeps the cash value (it was funding that benefit all along) — buying more is not the same as buying both.
